Lab-Grown Diamonds: Everything You Need to Know Before Buying in 2025
The diamond industry is experiencing its biggest transformation in over a century. Lab-grown diamonds now represent 20% of the global diamond market, and that number is climbing fast. Whether you're shopping for an engagement ring, anniversary gift, or simply curious about this revolutionary technology, this comprehensive guide will give you everything you need to make an informed decision.

What Are Lab-Grown Diamonds, Really?
Lab-grown diamonds are real diamonds—chemically, physically, and optically identical to mined diamonds. The only difference? They're created in controlled laboratory environments rather than deep within the Earth over billions of years.
Two main production methods exist:
CVD (Chemical Vapor Deposition): Carbon atoms are deposited layer by layer onto a diamond seed
HPHT (High Pressure High Temperature): Mimics the extreme conditions that create natural diamonds underground

Both methods produce genuine diamonds with the same hardness (10 on the Mohs scale), brilliance, and fire as their mined counterparts.
The Numbers Don't Lie: Market Growth & Consumer Demand

The lab-grown diamond market is exploding:
• Market size: Expected to reach $15.6 billion by 2030
• Growth rate: 22.5% annually through 2030
• Price advantage: 60-80% less expensive than natural diamonds
• Millennial preference: 73% consider lab-grown diamonds for engagement rings
